An attacker could exploit this vulnerability by sending crafted IKEv2 packets to an affected device. In the case of Cisco IOS and IOS XE Software, a successful exploit could allow the attacker to cause the device to reload unexpectedly. In the case of Cisco ASA and FTD Software, a successful exploit could allow the attacker to partially exhaust system memory, causing system instability such as being unable to establish new IKEv2 VPN sessions. A manual reboot of the device is required to recover from this condition."}, {"lang": "es", "value": "Una vulnerabilidad en la funci\u00f3n Intercambio de Claves de Internet Versi\u00f3n 2 (IKEv2) del software Cisco IOS, IOS XE, Secure Firewall Adaptive Security Appliance (ASA) y Secure Firewall Threat Defense (FTD) podr\u00eda permitir que un atacante remoto no autenticado provoque una fuga de memoria, lo que resulta en una denegaci\u00f3n de servicio (DoS). Esta vulnerabilidad se debe a un procesamiento inadecuado de los paquetes IKEv2. Un atacante podr\u00eda explotar esta vulnerabilidad enviando paquetes IKEv2 manipulados a un dispositivo afectado. En el caso del software Cisco IOS e IOS XE, una explotaci\u00f3n exitosa podr\u00eda permitir al atacante provocar la recarga inesperada del dispositivo. En el caso del software Cisco ASA y FTD, una explotaci\u00f3n exitosa podr\u00eda permitir al atacante agotar parcialmente la memoria del sistema, lo que causa inestabilidad, como la imposibilidad de establecer nuevas sesiones VPN IKEv2. Es necesario reiniciar el dispositivo manualmente para recuperarse de esta situaci\u00f3n."}], "lastModified": "2026-04-15T00:35:42.020", "sourceIdentifier": "psirt@cisco.com"}
